Question

A common application of discharge tubes is the fluorescent light tube. The electric current excites mercury atoms in the tube, which then return to their ground state by emitting photons of visible, and UV light. The specific energy of the photons corresponds to the difference between two allowed energy levels. One of the most intense visible lines of the Hg spectrum is at 436 nm. Calculate the energy of the 436 nm line.

Step 1

The wavelength (\(\lambda\)) of the photon is given as 436 nm. The energy (\(E\)) of a photon can be calculated using the formula: \[ E = \frac{hc}{\lambda} \] where: - \(h\) is Planck's constant (\(6.626 \times 10^{-34} \, \text{J} \cdot \text{s}\)) - \(c\) is Show more…
